Terrestrial table globe. Geographical details on the sphere include a very innovative feature, in that the lines of magnetic variation are depicted. The source used is given in a comment below the cartouche in a note stating, 'The lines of Magnetic variation are adopted / from Professor Peter Barlow's Chart in the Transactions / of the Royal Society for 1833'. The line of no variation is in the Indian Ocean. The location of the south magnetic pole is indicated close to the South Pole and it is labelled. In Africa, there is a comment: 'Supposed Sources of the Zaire or Congo', which are shown. In North America there are labels for 'BRITISH AMERICA', 'RUSSIAN AMERICA' for Alaska, and 'UNITED STATES'. There is note on the mutiny on the ship 'Bounty' and the retreat of the mutineers of the ship in 1789.

Notes on discoveries include, for example, 'Compact Ice Cook's highest South Lat 1774' in the south polar area. A total of nine oceans are named. There is a piece of gore which has been replaced.
